项目摘要
Surface thermodynamics and adsorption kinetics of small molecules, surfactants, peptides, and polymers are of fundamental importance in various chemical and biomedical engineering systems. A central property in surface thermodynamics is surface tension. From the behavior of surface tension, one can infer changes in surface chemical composition as well as molecular adsorption. In the next five years, we will focus our studies on the surface tension and its associated properties of select chemical systems, with four specific objectives:
1. Surface tension of small, volatile, amphiphilic molecules in aqueous and non-aqueous solutions. We will generate both experimental data and theoretical understanding of the surface tension under various conditions. The outcome of this line of research will have significant impact on our understanding of surfaces and emerging nanotechnology advances.
2. Surface tension of water-gas mixtures under conditions relevant to extra-terrestrial environments. We propose to measure the surface tension of water surrounded with vaporous CO2 (the main component of the Martian atmosphere) at varied temperatures and pressures. We will correlate the vapor pressure of CO2 with the water surface tension, providing data to predications of water content in the mesoporous soils of Mars.
3. Surface tension and associated properties of self/co-assembling peptides in aqueous solution. We will exploit our expertise in surface tension and extract important information about experimental conditions under which the newly designed amino acid pairing peptides assemble. The outcome will provide means to control peptide nanostructures for nano-biotechnology applications, especially for drug and gene delivery.
4. Surface tension of polymer melts in supercritical fluids under polymer processing conditions. We will measure the surface tension of polymer melts under high pressure and temperature, with/without mesoporous particles. The results will be explained by theoretical modeling based on self-consistent field theory. The outcome will have direct application to micro/nanocellular foaming of plastics.
小分子、表面活性剂、多肽和聚合物的表面热力学和吸附动力学在各种化学和生物医学工程系统中具有根本的重要性。 表面热力学的一个中心性质是表面张力。 从表面张力的行为,人们可以推断表面化学组成的变化以及分子吸附。 在接下来的五年里,我们将重点研究选定化学体系的表面张力及其相关性质,具体目标有四个:
1. 水溶液和非水溶液中小的挥发性两亲分子的表面张力。 我们将生成各种条件下表面张力的实验数据和理论理解。 这一系列研究的结果将对我们对表面和新兴纳米技术进步的理解产生重大影响。
2. 在与地球外环境有关的条件下水-气混合物的表面张力。 我们建议在不同的温度和压力下测量被气态CO2(火星大气的主要成分)包围的水的表面张力。 我们将把二氧化碳的蒸汽压与水的表面张力联系起来,为预测火星中孔土壤中的水含量提供数据。
3. 水溶液中自/共组装肽的表面张力及其相关性质。 我们将利用我们在表面张力方面的专业知识,并提取有关新设计的氨基酸配对肽组装的实验条件的重要信息。 这一成果将为纳米生物技术应用,特别是药物和基因传递提供控制肽纳米结构的手段。
4. 聚合物加工条件下超临界流体中聚合物熔体的表面张力。 我们将在高压和高温下测量聚合物熔体的表面张力,有/没有介孔颗粒。结果将解释的理论模型的基础上自洽场理论。 该结果将直接应用于塑料的微/纳米泡孔发泡。
